Awww Duck Tales was so great... well they're not paying royalties for the Turtles game as I know of... well most movie games aren't from the big N (usually Capcom or something)... I think they pay the royalties.

Doubtful that they're off limits but they'll all require Nintendo to obtain rights from whoever owns a particular license, which means games will end up costing more (ex: NES TMNT cost 600 points). So who knows what we'll see and when we'll see it.
